<LI>Send the native Pro/E file (if they have thePro/E translator, and you are o.k. with sending it).</LI>
<LI>Send STEP (if they have purchased the STEP translator).</LI>
<LI>Send ACIS (they can read ACIS format by default in Mastercam, no extra translator is needed).</LI>
<LI>Send IGES, again, no extra translator needed. It usually isn't too hard to convert it to a solid in Mastercam if they want a solid model to program off of. Many people just program right from the surface model, so IGES is o.k. to send as well.</LI>
If you cannot find out any information from themon what theyprefer, send IGES and let them figure it out for themselves.
